I have two different charts that give two different settings:
28 vents, 1.35 main and .55 idle or 32 vents, 1.45 main and .60 idle. Bought a set of EMPIs for a 2.0 which came with: 28 vents, 1.25 main and .52 idle Read MANY threads here, samba and type4forum on proper jetting and vents and they are all over the place. Would like to get these together and installed asap. Is the current set up good enough for daily driving to/from work? No track, no AX, just cruising around TN back roads. |

If they are 40s you want to start with a base of 28 vents , 115 main, 50 idle.
You can pull the main stack and solely drive around on just the idle to get a feel for the idle jets and where they will drop off. There are overlaps at each stage of the progression and you want to dial in each stage for best overlap in performance |
